Abstract
A system for accessing one or more artery in a head and neck area of a patient includes an access sheath including a tubular shaft having a distal end and a proximal end and a sheath lumen extending therethrough, the distal end of the shaft configured for placement through a puncture in skin and an adjacent arterial wall of a superficial temporal artery of a subject and to extend retrogradely within a portion of the superficial temporal artery of the subject, the proximal end of the shaft including a first connection portion, an intermediate portion of the sheath located between the distal end of the shaft and the proximal end of the shaft, the intermediate portion forming a curve of the sheath lumen, a resilient access-extension tube having an extension lumen extending therethrough, the extension lumen having a distal end and a proximal end, the distal end of the extension lumen configured to hydraulically couple to the sheath lumen at the first connection portion, and sealable opening carried by the access-extension tube and spaced from the distal end of the extension lumen, the sealable opening configured to allow insertion of an elongate medical device into the extension lumen …
